Radius-insolation flux figure of known exoplanets. The color-coding used is as follows: yellow, KELT-10b; green, HEARTS and SPADES surveys’ sodium detections (SPADES is a twin survey using a similar setup as HARPS-N at the 3.58 m telescope at La Palma); and red, WASP-127, the only nondetection from HEARTS. WASP-127 b has not been detected in HARPS data (Seidel et al. 2020c). However, by using VLT/ESPRESSO, Allart et al. (2020) established a tenuous signal below the detection limit of Seidel et al. (2020c).
